CLOSURE-APPLYING MACHINE.

Application filed July 21,

My invention relates to machines or tools for twisting together the ends of a loop made of a strand of string or other material so that the loop ends will remain in assembly. If the string of which the loop is formed is non-metallic, the twisted ends may be held in assembly by some suitable agency such as sealing wax. If the string is of metal, it is commonly called wire and the twisted ends thereof will remain in assembly without the aid of any additional means. I prefer to employ, metallic wire of simplicity in the manner of its treatment but the invention is not to be thus limited, nor is it to be limited to the use of strands that are circular in cross section.

The tool or machine of myinvention has been designed particularly for use in fastening the skirts of caps about the necks of bottles, such as milk bottles, having circumscribing beads at their mouths. In such use of the tool of my invention, the loop of the string is disposed to have its plane angular to the axis of the neck of .the bottle on the bottle positioner, the loop being in alinement with the bottle neck, the mechanism for forming the loop and bottle positioner being relatively adjustable to enable the location ofthe loop about the skirted closure cap after which mechanism operates to twist the loop ends-together to form the loop into a ring and to contract the ring about the skirt of the cap. The ends of the loop are preferably grasped by two grippers or holders, one for each loop end, an preferably both grippers or holders are thereafter revolved to loop together to bring the loop into the form of a circle completely surrounding the bottle neck, the action of the machine being such as to tightly draw the looped strand of wire or string about the cap skirt to bring the cap skirt into veryintimate contact with the bottle neck in the zone of the loop, the bead about the bottle mouth coacting wit the tightened loop to prevent the withdrawal of the cap.

In the preferred embodiment of the invention, the grippers or holders are provided'upon arms which are adapted to be crossed but which are initially uncrossed so that the bight' of the loop may be initially drawn tightly against one side of the cap twist the ends of the 1926. Serial N0. 123,936.

whereafter the arms are crossed to cross the ends of the loop, the arms being together revolved after the ends of the loop are crossed to twist the loop ends together. If the string is non-metallic, cement, such as sealing wax, is applied to the ends of the loop, where twisted, to maintain the twist. If the string is main without I have herein machine employing metallic wire ing the skirts of closure caps about the necks of bottles. In the machine, as I have preferably designed'it, there is included a guide which shapes a strand of such wire into a loop whose sides are spaced apart a distance greater than the diameter of the cap skirt; the grippers or holders bein arranged to grasp the ends of the wire oop. Mechanism is emplo ed for pulling1 upon the arms that carry t e grippers or 01 ers in a direction to apply the bight of the loop to one side of the cap skirt whereafter said arms are crossed and are together rotated to effect the twisting. In the preferred embodiment of the invention, the wire is fed from a reel and is severed after the initial formation of the.loop so that both ends of the loop are free to be readily twisted. Mechanism is employed having elements operated in orderly sequence for automatically positioning the bottles to receive the loops, to feed the wire to initially form the loops, to draw the initially formed loops t e agai t sldes of the bottle caps, to sever the addition of cement.

The bottles 1 are suitably supplied to a stationary deck '2 carried upon posts 3 which are supported by the base 4 of the machine. These bottles have caps -5 initially loosely applied thereto, these caps being desirably constructed as disclosed in United States Patentl,117,14fl, dated November 10 1914. The I of these ca; s are :to be tightened about the bottle necks y the machine of my invention so as to underlie the heads 6 about the bottle mouths shown by dotted lines in Fig. land in the broken illustration of the bottle appearing in Fig. 8. The bottles, with the loose c'aps thereon, are fed throu h the chute 7 in position to be engaged t e teeth of the star wheel 8 which serve to continue the travel of the bottles as they leave the chute and to direct the same individually onto the'vertically adjustable sections 9 of a disc-like table 10, these table sections constituting bottle positioners.

Any suitable mechanism may be employed I for operating the various operating elements that are located above the deck 2. In the embodiment of the invention illustrated, an

electric motor 11 may be employed for operating a main driveshaft 12'. Power is transmitted to this drive shaft at adjustable speed through the intermediation of any suitable speed changing gearing 13. The shaft 12 has a worm 14 thereon which is in mesh with a worm wheel 15. This worm wheel is fixed upon a shaft 16 on which there are also fixed the spur gear 17 and the table 10. This spur gear is in mesh with that is fixed upon a shaft 19 upon which shaft is also fixed the star wheel 8.

The bottle supporting table 10 is constantly turned and while turning, the sections 9 thereof are adually elevated from the plane, proper, o the table and gradually restored to this plane, the final capping operation that is to be described occurring when said table sections are in their upper limits of their movements.

I; provide a stationary cam track 20 upon which cam rollers 21 travel, to rise and fall. Each table section 9 is assembled with a cam roller so as to rise and fall therewith. As illustrated, each table section 9 is carried at the upper end of a spring barrel 22; A piston 23 is within the lower end of the spring barrel and is normallyheld in fixed relation therewith by means of a spring 24 which abuts at its lower end upon the piston and at its upper end against the top' end wall of the spring barrel. A link 25 connects each piston 23 with one. end of a bell crank 26 upon whose elbow the corresponding cam roller is journaled. The other end of this bell crank is ivoted upon an arm 27 depending from a ring support 28 which is fixed upon the shaft 16 and is located below the table 10.

As the shaft 16 turns, the cam rollers move bodily therewith over the cam track 20 to elevate and lower the table sections 9 to enable these table sections to function. As the shaft 16 and the parts thereon turn, the spring barrels 22 rise and fall due to the normally fixed relation ofv the pistons 23 therewith. These spring barrels are guided in their movement by bearings 29 in the bearing support 28. If, in the final capping operation, the bottles should encounter undue strain, the springs 24 will yield to prevent the bottles from breaking, the pistons 23 then rising in the spring barrels.

.A support 30 is in normally fixed relation with the shaft 16. This support has splined connection with the shaft 31 whereby it may be permitted movement lengthwise of the shaft. A large split nut 32 is screwedupon the upper. end of the shaft .16 and has tongue and groove connection with the support 30. so that this support ma be elevated and lowered along the shaft. A and wheel '33 is provided upon the nut 32 to facilitate the turning thereof. The support 30 carries the balance of the mechanism that is complemental to the tablelsections 9 and the mgchanis'm for fastening the caps upon the bottles. The support 30 is circular and concentric with the shaft 16. The periphery of this sup ort is closely received between rollers 34 that rojectlaterally from the sleeves 35, wliereby these sleeves are assembled with and are carried by said support. Thesesleeves are adapted to another spur gear 18 A 16 as indicated at the support 30, each table section 9 having a yoke individual thereto and located immediately above the same to be in line therewith. Each yoke straddles an opening 40 in -line with the corresponding table section 9, this opening being sufiiciently large to permit of the free passage of the bottle neck I therethrough. Each yoke carries a chuck 41 also constituting a bottle positioner and which is in the form of a shell in line with the corresponding underlying tablesection 9. The chucks are somewhat in the shape of bells that are flared at their lower ends and which are slotted at their lower ends to be spring-like. When the table sect-ions 9 are elevated 1 to a predetermined extent, the mouth ends of the bottles and the caps thereon are snugly received in the chucks so that the bottles and their caps are properly centered with respect to the wire or string applying mechanism of my invention. Each yoke carries a horse-shoe or looped shaped guide 42 formed with a wire receiving groove 43, the spaces within these guides 'being aligned with the corresponding chucks 41 and table sections 9. The loop shaped guide 42 is in alignment with the underlying bottle supporting table section when this table section is brought to rest to have the closure cap secured to the mouth of the bottle on this table section. Each chuck 41 and guide 42 is in association with the wire shaping and applying mechanism of my invention, there being one such mechanism individual to each such chuck and guide, numerals applied to each such mechanism being similarly applied to other of such mechanisms. Each wire applying mechanism, in addition to the guide 42, also employs two holders preferably in the form of grippers constructed as illustrated in Fig. 6. Each gripper is inclusive of a jaw 44 integrally formed with a gripper supporting arm 45 and a jaw 46 complemental to the jaw 44 and pivotally connected therewith by the pin 47. The jaw 46 of each gripper is formed with a cylindrical opening 48 through the front half thereof. The strand'of wire 49 which is fed from the reel 50 and is threaded through the openings 48 is received in the corresponding groove 43 to form a loop whlch is initially U-shaped as shown in Fig. 7. When the strand of wire-has received this initially U-shaped loop, it is severed by the knife 51 to make the loop of desired length and to give the loop its second free end, it

being preferable to havetwo free ends upon the loop before exercising the twistlng operation thereon. The wire cutting operation will be later more fully set forth. The loop which is formed in the strand is in a plane which is angular to the axis of the neck of the bottle on the positioner .in order to re ceive said bottle neck when the positioner and. loop forming mechanism have been suitably relatively adjusted along the bottle axis. After the loop has been severed, the ends thereof. are twisted together, by mechanism which will be described, to form the loop into a'ring and to contract the ring about the skirt of the cap.

After the wire cutting operation, the gripper or holder supporting arms 45 are moved from the initial positions shown in Fig. 7 to their crossed relation shown in Fig. 9 in which operation the jaws 46 are turned by the wire from their positions shown in Fig. 7 to the positions thereof shown in Figs. 9

and 10 whereby the ends of the wire loops are gripped. To ensure the hold of the grippers upon the ends of the wire loop, these loop ends are bent as indicated at 52.

shoes 53, 54 which are carried upon the support 30 the shoe 53 being carried by and integrally formed with the wire guide 55 that directs the wire from the corresponding reel 50, whilethe shoe 54 is carried by the corresponding yoke 39. The gripper arms, in being crossed, tightly encircle the wire loop about the corresponding bottle cap, the bends at 52 in the wire preventing the wire from being withdrawn from the grippers. After the gripper arms have been crossed to cross the sides of the loop as indicated in Fig 9, the gripper arms are turned to twistthe wire as indicated in Fig. 10, the gripper arms being turned, say, to. twist the wire twice, as indicated in F ig. 10. After the wire has been twisted as indicated in Fig 10, the rotation of the gripper arms is stopped whereafter they are uncrossed, as indicated in Fig. 11. In this uncrossing operation,tl1e twisting of the wire loses one-half of a turn and the bends at 52 are somewhat straightened. When the gripper arms are uncrossed, the jaws 46. are brought into their initial adjustment to permit of the passage of the wire therethrough, Figs. 7 and 11, by means of the stops 56 carried by the yoke 39.

The mechanism for operating the grippers and the knife 51 and the mechanism for feeding the wire will now be described. Each cycle of operations commences with the bottle that is placed upon the table section 9 by the star wheel 8, that is, each cycle of operations commences with the bottle that is in the extreme left hand position with the table sectionQj that supports the bottle, in its lowermost position. The table 10, to gether with its movable sections 9, and the support 30 are rotated together constantly and at a uniform rate. During the first portion of the turning movement of said table and support, about one-eighth .of a revoIuvThe bending of. the wire is caused by the 4 68 are in another zone.

he other'end of the grooves thereof matching to receive the wire together, meshing spur gears 59 and 60 respectively fixed uponand coaxial with said discs, a shaft 61 carrying the disc 58 and spur gear 60, a bevel pimon "62 fixed upon the 2S aft 61, a bevel pinion 63 meshing with the pinion 62, a mutilated spur pinion =64 fixed upon the shaft that carries the pin- 8 ion 63, and the stationary .arcuate gear segmentor rack 65 carried-by the normally :sta-

tionary gear carrier 66, this gear carrier bemg earned by the sleeves :so that it may be adjusted, together with the support 30, to suit the height of bottles being operated u n. A bracket 67 carries the shafts upon which the elements58 to 64 inclusive, of each wire feeding mechanism, are respectively fixed. A disc 68 is fixed upon and is coaxial with each mutilated pinion 64. The pinions 64 and rack 65 are in one zone and the discs Each disc 68 has i a, flattened edge portion 68 which is engageable with a normally stationary segmental traek 69 in the same zone therewit 1 the track 69 and rack 65 being coaxial. During the rotation of the support 30 and table 10, the mutilated pinions 64 are brought into mesh with the rack 65, this meshing occurring during the second one-eighthrevolution of said support and table. During this oneto eighth of a revolution, the wire feeding discs 57 and 58 are turned to feed the wire through the guide 55 alength-corresponding to the length of the 100 of wire that is to be wrapped about a bott e neck. At the con"- clusion of this one-eighth of a revolution, the

flattened side of the corresponding disc 68 is brought into engagement with the arcuate track 69 to prevent further rotation of the corresponding pinion 64 so that the correspondlng wire feeding mechanism will be arrested from further feeding operation until the next cycle of o erations. After the wire has been thus fed theiknife 51 is operated to shear the wire, this operation 5 occurring during a few degrees of the succeeding" turning movement of the table 10 and su port 30. The knife 51 is carried by one en of the bell crank lever 70 which is ivoted at 1 its elbow u on the bracket 71.

ll.crank carries a roller77. A s ring 73 presses the bell crank in a counter-c ockwise direction, Fig. 12, to an extent which is limited by the engagement of the lug 74 onthe bell crank wlth the ll bracket 71.. The various rollers 7 2 upon the various hell cranks 70 are normally positioned to be in the same zone by the various springs 73. A single cam post 75, common to all the rollers 72, is stationarily mounted upon the stationary gear carrier 66 and extends into the normal zone of the'rollers 72 to an extent to depress the roller presented thereto sufficiently to move the corresponding knife 51in a wire shearing direction. After the post 75 has been passed, the corresponding s ring 73 restores the corresponding Ikni e to normal position.

During the next few degrees of the turning movement of the table 10 and support 30, the gripper arms 45 are crossed. To this end the two gripper arms of each wire applying mechanism are journalled on spaced apart pins 76 carried by ahead or support "77 which is preferably in the form of a rotatable yoke. The pivoted-ends of the arms are provided with arcuate gear segments 78 that :mesh with the racks 79 carried upon and preferably integrally formed with a reciprocable rod 80. When the arms are to be adjusted from the uncrossed position ill-ustrated in Fig. 7 to the crossed position illustrated in'Fig. 9, to interchange the positions of the grippers respect (to support 77, the rod 80 is moved inwardly and when the arms are to be uncrossed, said and is moved outwardly. As the arms are being crossed, the angular ends thereof contact with the skirt of the cap 5 in the region where the wire is initially crossed so that the cap skirt is depressed at this place against the bottle neck. By this means, the cap skirt is prevented from hunching. where the wire is crossed and sufiicient clearance is afforded between the wire where crossed and the cap skirt to permit the twisting of the wire to come close against the cap skirt as illustrated in Fig. 10. Means for moving the rod 80 of each wire applying mechanism is inclusive of a fixed cam 81 having a cam groove receiving a roller 82 upon one end of an arm 83. The other end of this arm is coupled with a shaft 84 through the intera nut 88 on the rod, and an arm 89 fixed upon the shaft .84 and pressed upon by the other end of the spring 87. A square shaft 90 is received and slidable within a sleeve the upper end of .the extension 92 of the 91 having a square bore and carried upon shaft 84. An arm 93 is fixed, at one end,

upon the upper end of shaft 90 and carries a pin 94 at its other end. This pin 94 is received within an annular roove 95 formed in a collar 96 that is secured upon the corresponding rod 80. The shafts 84 pertaining to the various-wire applying mechanisms on the machine are journaled in the bearing support 28 to turn with respect thereto and to travel therewith. The cam 81 being stationary, the rods 80 of the various wire applying mechanisms are lineally moved at proper intervals to cross and uncross the gripper arms 45. The gripper arms which have been crossed to draw the loop tightly against and almost completely about the bottle neck, as indicated in Fig. 9, are together turned to twist the wire whereafter these arms are uncrossed. The mechanism for turning each pair of gripper arms is inclusive of the head or support 77, the sleeve extension 94 in which sleeve extension the corresponding rod 80 is slidable, the roller bearing 98 in which said sleeve extension is journaled, this roller bearing being mounted upon the support 30, the mutilated bevel pinion 99 fixed upon said 2 sleeve extension and employed to turn. such extension to turn the corresponding gripper arms at the proper time, the arcuate or seg mental rack 100 upon the normally stationary gear carrier 66, the disc 101 also fixed upon said sleeve extension 97 and located alongside of said pinion 99, and the segmental arcuate track 102 located in a different circle from the circle that contains the rack 100, these circles being coaxial. When the support 30 has been turned sufficiently to complete the crossing of the jaws, the pinion 99 that is to be operated in the cycle of operations being described, engages the rack 100 whereby the corresponding head 77 is turned to turn the gripper arms to twist the wire as indicated in Fig. 10. When the gripper arms have been turned twice, the flattened edge of the disc 101 is brought into engagement with the track 102 to prevent the pinion 99 from being further turned in order to arrest further rotation of said arms.

In Fig. 13, rack 100 is not illustrated in the position it actually occupies in Fi 8 but is so shown for sake of illustratlon,

Fig. 13 being correct in this respect if it is not coupled with Fig. 8. In Fig. 13, the

pinion 99v is entering upon its revolution.

The twisting revolutions of the gripper arms are concluded shortly after the first half of the cycle of operations being described has been completed. During the succeeding few degrees of turning movement of the support 30, the arms,- which are not now being revolved, are uncrossed by the outward movement of the corresponding rod 80, a result which is due to the coaction of the cam elements 81 and 82 which control said rod in the manner hitherto described.

By the time the support 30 has completed three-quarters of its revolution, the bottle having the cap secured thereto by the twisted 'wire is lowered, the corresponding cam .roller 21 ;then riding down on the cam track 20.

said support.

During the remaining quarterof the revolution of the support 30, the fully capped bottle is discharged from the table 10 by the star wheel 103, this star'wheel serving to transfer the bottle to a chute 104 which returns the bottle to the table 2 from where it canbe removed by an attendant.

The table 10 with its section 9 are preferably rotated to bring the bottle to the various stations at which the wire is fed, cut, twisted and released from the grippers or holders; but the invention is not to be limit- 7 ed to the direction of travel of the bottles and the table members 9 to the various stations where the wire is operated upon in the manner described.

While the machine herein disclosed includes a bottle positioning table member which travels with respect to a point in space to bring the bottle to various stations where the various operations may be performed, it is obvious that the invention insaid arms; and a reciprocable rack member meshing with said gears to interchange the positions of the holders with reference to 2.
